A simple solution for the kernel stacks is to use the user stack in
kernel mode, this is:

DS = ES = Kernel segment
SS = User data segment.

Of course, this leads to problems. And the current kernel will require
very careful inspection and corrections. But I think this is doable by
enforcing some simple rules.

What do you think?
